Why compare long excursion 10's to regular 15's. That's comparing apple to oranges, right? If you're going through the trouble of building a WO for 15's because you want it to be louder, you might as well load it with powerful 15's just as would have loaded your 10" WO with powerful 10's.

why, why, why. the mods are not needed. wickedone with dhm 108 s, a nine volt driver and one kicker 500.2......160dbs.so clear, so tight and hits so fucking hard you ll almost puke at times!!!!!! i have heard many many sub applications from 100$ to 5000$ and nothing sounds like this box driven correctly. my hats off to steve time and time again... have fun and peace....

Back to comparing long-excursion 10s vs. 15s there is a very good reason to go with larger drivers. The less the excursion the less the distortion and the less the strain on the driver. "Effortless" is the word for all the best bass reproducers. The less the driver moves to achieve the SPL the better.

nice work guys, i was wondering what kindof mounting depth you had with the baffle at that extreme on an angle. Maybe i could invert the sub and fire into the sealed area? If i have to go with 12's my feelings wont be hurt too bad but having 15's would be nice.

[/quote] I built a 12 inch version with MTX thunder 9000's for a friend. MTX amp with 600 watts RMS bridged at 4 Ohms. I mounted the speaker inverted and in reverse phase. I calculated the speaker displacement and the amount of volume I lost in the sealed side when angling the baffle. Turning the speaker around kept the box volumes the same as before modification so the tuning would be the same....although I modded the port area to allow more airflow. I also added some bracing in the ported side to take up some space....just try to keep your box volumes equal in ratio. Also a note of interest....Horn mouth size is in direct ratio with cone area. 15 inch speakers have twice the cone area as ten inch drivers. In my opinion the horn mouth should be twice the size then.... You decide. ???
